CrowdStrike Confirms Chinese AI Agent ARTEX Attacked Seven South Korean Banks; 68,000 Records Leaked Before Project Went Closed-Source
A China-linked actor used the open-source AI agent ARTEX, chaining DeepSeek V4.1-Flash, GLM-5.3, Grok 4.6 and Anthropic Claude Code, to breach at least seven South Korean financial institutions between late September and early October 2026, exposing the data of 68,000 customers. CrowdStrike's report on the campaign highlights how multi-model agentic tooling is outpacing traditional network isolation defenses.
